Picture introduction: In order to prevent the Japanese army from taking advantage of the situation, the Fengtian government decided to keep Zhang Zuolin's death secret. The Marshal's mansion is still brightly lit and filled with haze. Medical officer Du still goes to work on time every day and fills in medical records. The kitchen still delivers three meals a day on time. No one in the family cries or wears filial piety. The Japanese side sent people every day to "condolence and ask for a visit," but they were all "politely declined." The fifth lady who presided over the housekeeping wore heavy makeup and calmly dealt with the Japanese ladies who came to pry into the truth. At the same time, the Fengtian authorities ordered martial law throughout the city to stabilize the situation. Since the Japanese army did not know whether Zhang Zuolin was killed, they did not dare to act rashly. It was not until Zhang Xueliang sneaked back to Shenyang that the news of Zhang Zuolin's death was announced on June 21.
